Specification forming part of Letters Patent No. 171,660, dated J anuary4, 1876; application led November 24, 1875.

To all whom it may concern:

Be it known that I, SAMUEL H.. G1LMAN,I

- Fig. 4, an inverted plan view of my improved machine. Fig. 5 is adetail View of a part of the same.

The object of my invention is to cut off the ends of bands oncotton`ba1es,and at the same moment punch the end cut off, and thusleave it ready to be riveted to another similar piece or pieces to forma new band, thereby saving the labor of one hand usually required topunch the ends cut oi' when cotton is compressed, and the original bandsthereby shortene In the drawings, A represents a frame, provided uponone side with a vertical dovetail groove or way, a, the yokes I I, andthe bed D. E is a knife-edge on that side of the bed D nearest thegrooves a, and fis an opening in the bottom of the bed, through whichthe pieces or chips fall as they are punched out of the band by thepunching device which .Works in the guide G. Between the bed D and theupper portion of theframeA, of which it forms a part, there is asuflicient space, d, made by cutting away the central section, to permitthe baud, which is to be cut and punched, to be placed underneath the-cutting and punching device, and also to allow the latter sutlcientplay to operate properly. B is a tool designed to work in the dovetailgroove or way a, and extends down from the circular head e, and carriesa knife-edge, F, a punch-stock, C, and a handle, Q. These various partsmay all be combined in one piece or made separate, and afterward unitedin any, proper manner. X is a shaft passing through the circular head eof the tool B, and is provided upon its ends with eccentrics X', whichwork in the yokes I. Upon one end of this shaft isa handle, L, by meansof which the tool is operated. The knife-edge F on the ytoolB has anupwardinclination Ifrom its inner to its outer edge, and in the act ofdescending tits closely against the knife edge E on the bed D, so thatwhen the tool is operated the two knife-edges pre- Sent theircutting-edges as shears Ato cut the bands introduced between them. Apunch,

y, is secured in the foot-of the stock C, immediately above an opening,f,in the bed D, of a size corresponding to that of the rivet-holes to bemade. This opening f has a downward are, to permit the escape ofthechips or pieces of metal during the operation of punching.` It will bereadily perceived that the punch-stock C, being firmly attached to andmade part of the tool B, works with it, and that the process ofcuttingand punching the band is simultaneous.

The operation of my improved machine for cutting and punching the endsof cotton-bale ties is as follows The portable tool being constructed asa whole, as shown in Fig. l, is either slipped onto va band, or a bandis taken into the space d, so that its end which is to be cut off restsacross the knife-edge E and upon the bed D immediately underneath thepunch g. The handle L is then brought downward, as indicated by thearrow, until it reaches a position nearly opposite that which itformerly occupied, as shown by the dotted lilies, Fig. 2. By thusdepressing `the handle L either forward or backward, the eccentrics X Xconfined in the yokes I I force down the tool B along the groove a, andthe punch-stock C' through the guide Gr, and bythe time the handle hasarrived at the position indicated in dotted lines, Fig. 2, the twoknife-edges E and F have cut or sheared the band in two, while the holefor the rivet has at the same time been made by the punch g. This beingdone, on the return of the handle L to an upright position, the tool ismade ready for a second operation similar to that already described.

My machine will be found of great use and practical benefit, beingcomparatively simple in i itslconstruction, not liable to get out ofrepair, i and adapted to be used as a-hand-tool, readily l carried fromplace to place.`

Having thus described my invention, what I claim as new, and desire ,tosecure byLetters Patent, is

1. A hand-tool for cutting and` punching i cotton-bale bands and Aotheri analogous uses,

`comprising a punch and die, a pair of shearblades, mechanism foractuating one of said shear-blades, and the punch or die, and a handlefor conveniently applying and holding said tool toits work,substantially as described.

2. The combination of the shear-blade B, punch-stock C, and handles Q,with the movableframe A, bed D, shear-blade E, and punchdief,substantially as and for the purposes described. y

3. The combination, in a'portable hand-tool,

- purposes described.

of a device consisting ofY a shearfbladeand a punch and `punch-stock,eitherintegral or permanently united, with a' device consisting of ashear-blade and punch-die, also integral or permanently united,mechanism for actuating i one of saiddevices so as tocause it to cut andpunch a piece of. metal presented toit, and a handle for convenientlypresenting and holding the combined device to theplate to be operatedon, substantially as described.

4. The combinationof thelshearing and punching device, the handle, theeccentric, and the crank, substantially as and for the WSAMUL H. GILMAN.
